It fails when looking for the gateway. ( i have specified the gateway="eth1/<ip>" ) in conf.d/net because it seems unable to use the same ip/gateway that eth0 uses.
So i tested it by adding another ip there as if i had another router/gateway and it worked.

Unless i can work this around in with gentoo.... the other fast and possible way is to had another router to the network to be setup between my box and the main router. ( this option does suck a bit )

AFAIK you can't have two nics on the same logical network connected two different physical networks...

I suggest bring eth1 up but without any ip configuration, then bridge it with vmware nic (through vmware-config.pl), then in vmware you'll end up with only one interface which can be setup same as eth0 in gentoo (it won't be complaining)
